linux - 无法读取文件 Datadog 代理

Question

按照本指南设置日志文件的 dd-agent 权限后 https://docs.datadoghq.com/logs/guide/setting-file-permissions-for-rotating-logs/ ，我仍然得到:

- Type: file
  Path: /home/ubuntu/Projects/livestream/nohup.out
  Status: Error: cannot read file /home/ubuntu/Projects/livestream/nohup.out: stat /home/ubuntu/Projects/livestream/nohup.out: permission denied
  BytesRead: 0
  Average Latency (ms): 0
  24h Average Latency (ms): 0
  Peak Latency (ms): 0
  24h Peak Latency (ms): 0

我已确认已设置权限:

# file: Projects/livestream/
# owner: ubuntu
# group: ubuntu
user::rwx
user:dd-agent:r-x
group::rwx
group:dd-agent:r-x
mask::rwx
other::rwx

ubuntu@ip-172-31-38-150:~$ getfacl Projects/livestream/nohup.out 
# file: Projects/livestream/nohup.out
# owner: ubuntu
# group: ubuntu
user::rwx
user:dd-agent:r-x
group::---
group:dd-agent:r-x
mask::rwx
other::rwx

getfacl Projects/
# file: Projects/
# owner: ubuntu
# group: ubuntu
user::rwx
user:dd-agent:r-x
group::rwx
group:dd-agent:r-x
mask::rwx
other::r-x

sudo systemctl restart datadog-agent
sudo datadog-agent status

它无法读取文件可能发生了什么？

我在 Ubuntu 22.04 上遇到了类似的问题。我解决了添加dd-agent在 Ubuntu 组上

sudo usermod -aG ubuntu dd-agent
